Terbutaline elixir in preschool children with chronic asthma

Area of Science:

• Pediatric Pulmonology
• Pharmacology

Background:

• Asthma is a common chronic respiratory disease in children.
• Effective bronchodilators are crucial for managing pediatric asthma symptoms.

Purpose of the Study:

• To evaluate the efficacy and safety of terbutaline in asthmatic children.
• To determine the optimal dose and duration of terbutaline treatment for pediatric asthma.

Main Methods:

• Double-blind, single-dose trial with terbutaline (25, 50, 100 ug/kg) and placebo.
• Measurement of pulmonary index score and respiratory resistance (Rrs) via forced oscillation.
• Nine-week single-blind trial assessing clinical wheezing prevention.

Main Results:

• Terbutaline significantly decreased pulmonary index score and Rrs for up to 4 hours post-dose.
• A dose-response relationship was observed, with significance between 25 and 50 ug/kg at 4 hours.
• Terbutaline prevented clinical wheezing in 5/8 patients at 50 ug/kg tid and 2/8 at higher doses.

Conclusions:

• Terbutaline demonstrates significant bronchodilatory effects in asthmatic children.
• Terbutaline is effective in preventing wheezing episodes in pediatric asthma.
• Terbutaline is generally well-tolerated in this age group.
